Another of the more difficult tasks that must be assumed in a wise courtship program is discovering whether there are in the person one is beginning to like incentives toward growth. There is one certain thing in any marriage: it is impossible for those who enter such an alliance to remain stationary; either they grow in character or they lose ground. The mere possession of ambition is not evidence of the desire to grow up emotionally. One has to probe the ideals of the other person. The question is, "Does he or she have the character-vitality to develop emotional maturity?" If this is lacking, successful marriage is seldom achieved, and for one who has gained this trait to be tied to a spouse who cannot attain it is tragic for the well-matured person.
